Given numbers are 843,391,667,238
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 843,391,667,238 is 133822878.
Find LCM of 843,391,667,238 with Prime Factorization
| 17 | 843, 391, 667, 238 |
| 23 | 843, 23, 667, 14 |
| 843, 1, 29, 14 |
Multiply the prime numbers at the bottom and the left side.
17 x 23 x 843 x 1 x 29 x 14 = 133822878
Therefore, the lowest common multiple of 843,391,667,238 is 133822878.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
843 x 391 x 667 x 238 = 52324745298
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
843 : 1, 3, 281, 843
391 : 1, 17, 23, 391
667 : 1, 23, 29, 667
238 : 1, 2, 7, 14, 17, 34, 119, 238
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 843,391,667,238, is 1.
Now, the common factors can be found like this.
843:3x 281
391:17x 23
667:23x 29
238:2x 7x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 23 = 391
Therefore, the value for common factors is 391.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 52324745298/(1x391)
LCM = 52324745298/391
LCM = 133822878
Thus, we can understand that the LCM of 843,391,667,238 is 133822878.
